Julian S. ★★★★★

The pan head sits flat without stripping, and the phillips drive catches cleanly every time—no cam-out frustration. The zinc finish held up fine during assembly, and having 200 in one package means I won't run out mid-project.

Penelope ★★★★★

The zinc plating on these #4-40 screws is nice and even—no burrs or rough edges on any of the 200 pieces I checked. They seated perfectly into my project’s tapped holes without binding, which saved me a lot of time.

Violet ★★★★★

Installed a dozen of these for a small electronics panel, and the integrated washer on each SEM screw saved me from having to grab a separate lock washer. The Phillips drive engaged cleanly without any cam-out. Exactly what I needed for that particular thread count.
